System of Equations solutions

Hello, how do I go about solving this system of equations? Angle measurements are in radians. I will need to use this method again for many values other than 660 in the second sine function. For reference, I'm using this method to find the wavelength of the function $f(x) = \sin{(2\pi440x)} + \sin{(2\pi660x)}$

This is the system.
$\sin{(2\pi440x)} = \sin{(2\pi660x)}$
$\sin{(2\pi440x)} = 0$
$\sin{(2\pi660x)} = 0$

Thank you for your help.
